That is a dog looking at someone he loves. I really miss our little Jack Russell, who died in June of a heart attack with a secondary diagnosis of breast cancer. I have cats for decades, but the difference in the animals' reaction to their peoples' homecoming is far divergent.
Go play with the pups.
Sit by the old folks.
Nuzzle someone who's sad.
Or take a nap.
Life is full of choices."
